5 years ago got Glandular fever and was not picked up by GP who said it was
a cold. Exercised  during the bout and hasn't been the same since. She had
all common CFS symptoms and was diagnosed by a specialist GP after 6 mths of
tests.

She has been to
1 psychologist tried to anti-depress the problem out of her.
1 neurologist with MIRs and several expensive dna type tests
3 naturopaths
1 acupuncturist
4 GPs
4 optomolgists

Really the fatigue has passed but she was left with reduced vision she sees
more clearly in a specific area and surrounding vision blurry. This is also
shown up as a convergence issue where she cannot see 3d as as she career is
a medical scientist this stopped her working. Any time spent trying to read
or use PCs makes her fatigued. If she just sits around she feels ok but any
eye use wears her out. This picked up by an optometrist as the optomologists
all said her eyesight was fine till we asked to test convergence.

Recently has tonsils removed due to 5 years undetected tonsil issue (missed
again by GPs) and after the  operation while on strong painkillers and other
stuff she felt fine and actually was heading upward in her eyesight issues .
Unfortunately pain came back and CT scan showed Eagle syndrome so before she
goes to surgery the ENT specialist wanted to have a neurologist reassess her
wrt neuralgia and other issues . Thus the Indomethacin which seemed to help
pain and her eyesight but she couldn't keep her eyes open.

Her issues do not sound like the issue you are having. Most Doctors treat
her as a patient trying to milk the system . All she wants is to be able to
work more than the 3 hrs a week she can force herself into.
